<p align=center><b>Data alignment</b></p>
<p>The Berkeley DB access methods provide no guarantees about byte alignment for
returned key/data pairs, or callback functions which take <a href="../../api_c/dbt_class.html">DBT</a>
references as arguments, and applications are responsible for arranging
any necessary alignment.  The <a href="../../api_c/dbt_class.html#DB_DBT_MALLOC">DB_DBT_MALLOC</a>,
<a href="../../api_c/dbt_class.html#DB_DBT_REALLOC">DB_DBT_REALLOC</a> and <a href="../../api_c/dbt_class.html#DB_DBT_USERMEM">DB_DBT_USERMEM</a> flags may be used to
store returned items in memory of arbitrary alignment.</p>
